Application ma October 11, 1909. Serial No. 522,130.

To all whom it may concern:

Be it known that I, JEROME B. FELLOWS, a citizen of the United States of America, and resident of Boston, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Lawn-Sprinklers, of which the following is a full, clear, and exact description.

This invention relates to improvements in water sprinklers to be used especially on lawns, of a kind in which are comprised a lurality of differently directed and revoluble water delivery members, such as nozzles or sprinklers, and means operable by the water supplied to the apparatus by a hose, and which asses to and through the delivery mcm ers for causing the revoluble movements of the latter.

The objects of the invention are to provide a sprinkling apparatus having revoluble delivery members whichvare so adjustable that one stream or spray may be thrown in a wide circular distribution to cover a large areawhile another stream or spray may be thrown for circular distribution in a smaller area and within that covered by the first delivery member; and to provide a sprinkling apparatus constituted by parts which by the construction and arrangement thereof renders the s rinkler certainly o erative irrespective o the variations in t 1e directions in which the streams or sprays are thrown.

Other objects for the attainment of advantages and the general efliciency of the sprinkler are acquired in and by the organizatioz' of the operative arts of the appa- Eatus as will be hereina er renderedmaniest. 3

The invention consists, in a sprinkler, in the combination and arrangement of parts and the constructions of certain of the parts substantially as hereinafter described in conjunction wlth the accompanying drawings and set forth in the claim.

In the drawings :Figure 1 is a plan view of the improved a iparatus with the delivery members or sprin rlers thereof shown as in one of the extremes of the positions in which they may be adjusted. Fi 2 is a lan view of the body or casing of t e sprin ler with the cap or cover and parts carried thereby removed. Fi 3 is a vertical sectional view as taken on fine 3-3, Fig. 1. -Fig. 4 is a view showin an interchangeable nozzle on one of the elivery members instead of a sprinkleni Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents the body of the apparatus, the same comprising a casing of a general cylindrical shape having a comparatlvely slight dimension in the direction of its axis. The casing is provided at one side with a hub a for receiving a coupling connection therewith of a hose, the

passage a through such part being tan enthe cap and body of the casing for making the closure absolutely tight. The water outlet conduit comprises a pipe B which extends upwardly from communication with the interior of the casing at the top thereof and is provided with branches d d on which are rotativel adjustable water delivery members 0 which may comprise or are equipped either with sprinklers as shown at e, or with nozzles e, as represented in Fig. 4.

In order to constitute an efiicient bearing for the rotative upstanding pipe B, the cap of the casing is made with a tubular vertical extension f having external screwthreads g at its upper end portion and provided with an internalshoulder h 'ust below its upper end; and the pipe B as the lower portion thereof located within said tubular extension ff, its end extending slightly below the top 0 the cap and into the chamber in the casing; and said ipe B has an external flange '11 which has a earin support on the aforesaid internal flange o the upstanding tubular part f; and the coupling rm j, the internal flange -j of which encircles t e pipe branches d d of the B by the internal screw threads on its body, has a screw engagement with the threads on the upper end portion of the tubular extension 7, and a packing j is interposed between the internal flange 7' of the coupling ring and the upper end of the tubular extension f, 'a water-tight connection being thus made.

The motor, which is driven by the water entering and passing through the casing comprises, as shown, an axially vertical water wheel D made With'a central hub is with a. surrounding frame andwith radial blades k, the widths or vertical dimen sions of which are nearly as reat as the vertical space within the 1101 0w circular body A. The said water Wheel D is rovided with an arbor or center shaft la w ich is made as one with the wheel, such shaft having journal bearings in sockets therefor in the base and cap of the casin The said arbor is provided with a fixed inion m near its upper end, but slightly be ow the under surface of the cap B, with which meshes a spur gear wheel at on a stud m depending a short distance below the cap, said spur gear having made as one and concentrically therewith a pinion m which is in mesh with a spur ear wheel m ailixed on the lower end of the pipe B which rotrudes slightly below the under surface of the cap.

The opposite obliquely upwardly arranged pipe B are, as shown, arranged at angles of 45 degrees to the axis of the pipe; and the water'delivery members C C which are coupled to said oblique branches by the couplin rings n n have their portions 14, by whic they are coupled, angular to their outer portions 1,-the portions 14 and 15 of the water dellvery members being also here shown as at angles of 45 degrees to each other. The coupling rings at while having the capability of mak-' ing water tight connections between the deivery members G and the branches d of the pipe B also constitute means for permitting revoluble adjustments of the water delivery members relatively to the pipe branches and for tensioning or confinin such membersm their individually adjustc POSitlOHS. With a hose for supplying water connected by the coupling rin s a, the water Wlll sidewise and more or ess tangentially enter the easing and drive the water wheel around; the water wheel constitutes a motor, which, through the gearing, imparts a slow steady rotary motion to the upstanding pipe B which is the conduit through which allot the water, entering the casing, and dmvrn the water wheel passes; and the water Wll in passing through the delivery members be thrown in different lines laterally related to the axis of the outlet pipe. Each water delivery member 0 may have an ad ustment,

' members vthrough the other,

so that the line of delivery is horizontal and at right angles to the axis of the pipe or vertical y in ines parallel with, and offside from, the axis of the ipe, or obliquely upwardly at an angle 0 any degree between horizontal and vertical lines; and with nozzle or sprinkler ends directed either forwardly or rearwardly relatively to the direction of rota movementpf the water outlet pipe by w ich they are carried. The delivery members may be adjusted in positions to have correspondin an les so that the stream or s ray of hot W51 be correspondlngly ro ected, or one may be arranged or t rowing outwardly in a maximum or considerable degree while the other delivery may be arranged for throwing a stream or spray within a circular area circumscribed by that covered by the given first delivery member; and one of the delivery members C may be employed as or equipped with, a nozzle, while the other may be equipped with a sprinkler head. In short, the adjustments and relative arrangements of the delivery members may be so varied and many that while too numerous to herein mention, it will be a preciated that they constitute very valuab e and attractive capabillties in the sprinkler a paratus; and it may be furthermore stated that in this sprinkler irrespective of how the delivery may be relatively adjusted, and even if they are set in such opposition that thereaction or back ressure of the stream passing from one might be diametrically opposite the reaction of the stream passin there can be no 'dea locking or rendering of the sprinkler inoperative, as has been the case in certain other sprinklers relying upon the reaction or back pressure of t e water for insuring the revoluble movements of the sprinklers or nozzles, because in the present apparatus the motor which is positively driven by all the water passing through the casing rotatively drives, with certaint the outlet pipe B by which the water delivery membersare revolublyecarried.

I claim I v v In a water sprinkler, in combination, a casing having a sidewise opening water inlet passage, having at its top a tubular vertical extension externally screw threaded and provided with an internal shoulder below its upper end, a pipe, the lower ortion of which is located within said tubu ar extension, its lower end being located within the casing while a portion thereof within and near the to of said tubular extension has an external iiiinge having a bearing support on the aforesaid internal flange, a cou pling ring provided with an internal flange externally encircling said ipe and said ring screw engaging the three s of said tubular extension, said pipe having upwardly oblique branches at its upper end and water delivery members, the inner end portions of which are coupled to said branches and are angular to the outer end portions of said members, :1, motor in the casing rotatively operable by the water entering the latter, and driving connections between said motor and the lower end of said pipe which protrudes into the upper portion of the casing. 10
